Determination of parathyroid hormone levels in fine needle aspirates of ectopic parathyroid glands.
Sir, Progressive image technologies are improving the accuracy for determining the localization of enlarged parathyroid glands (PTGs) in hyperparathyroidism (HPT). However, the identification of an unusually located cervical nodule as an ectopic PTG remains uncertain. The measurement of parathyroid hormone (PTH) in the aspirated material with a fine needle has shed light on this diagnostic diff...
متن کاملParathyroid hormone without parathyroid glands.
In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...
متن کاملPreoperative localization of suspicious parathyroid adenomas by assay of parathyroid hormone in needle aspirates.
OBJECTIVE To determine the usefulness of parathyroid hormone (PTH) measurement in needle aspirates of a suspicious neck mass to confirm its parathyroid nature in patients with primary hyperparathyroidism. METHODS Thirty-three patients with surgically proved primary hyperparathyroidism were submitted to neck ultrasound (US), parathyroid scintigraphy, and assay of PTH in the aspirate (PTHa) of ...
متن کاملUltrasonically guided fine needle aspiration of suspect parathyroid tissue to determine parathyroid hormone concentration.
Ultrasonically guided fine needle aspiration of suspect parathyroid tissue to determine parathyroid hormone concentration Since the study of Arima et al,1 several reports have confirmed that enlarged parathyroid glands can be located preoperatively using ultrasound. A general problem has been the difficulty of distinguishing nodular thyroid lesions from enlarged parathyroid glands.2 3 We report...
متن کاملFine Needle Aspiration Cytology of Parathyroid Lesions
BACKGROUND There has been an increase in the use of fine needle aspiration cytology (FNAC) for the diagnosis of parathyroid lesions (PLs). Differentiation between a thyroid lesion and a PL is not easy because of their similar features. We reviewed parathyroid aspirates in our institution and aimed to uncover trends in diagnostic criteria. METHODS We selected 25 parathyroid aspirates (from 6 m...
